More about
the Allis-Chalmers 7020

Production of the Allis-Chalmers 7020 Tractor started in 1978 and continued until 1981. The Allis-Chalmers 7020 Tractor first came out at a price of $39,378, but you might be one of the lucky ones who found a good deal lower than that. The bad news is that, like any other tractor, the Allis-Chalmers 7020 Tractor needs spare parts to keep it running; the good news is that we have all the parts you need at 60% off dealer prices in our inventory. Sometimes, the parts compatibility is determined by the serial number of your Allis-Chalmers 7020 Tractor, and that info should be listed on the part fit notes. If you don't have the serial number of your tractor, you can find it above PTO shield. The serial number starts from 1317 for a 1978 model, from 2732 for a 1979 model, from 3842 for a 1980 model, from 4710 for a 1981 model. They also have differential power wet disc brakes. The type 3/2 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 540/1000 rpms.
